Application October 7, 1947-, Serial No'. 7.783-21 2 Claims.

. The present invention relates to new and useful improvements in dispensing devices for tooth powder and similar material and more particularly to a device of this character for dispensingmeasured quantities of the powder.

An important object o-f the invention. is to provide a dispenser for powder including a powder container having a measuring chamber therein controlled by a plunger operating oppositely opening and closing proportionating valves to dispense measured quantities of powder from the container together with means for venting the container as well as the measuring chamber to prevent creation of vacuum therein which might interfere with the eiiicient dispensing of the powder.

A further object of the invention is to provide a -powder dispenser of this character and in which the. powder container is constructed to provide a glass holder, tooth brush holder and a wall bracket as a unitary part of the dispenser.

A still further object is to provide a device of this character of simple and practical construction, which is neat and attractivein appearance, efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the ypurposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein. like numerals refer to like parts throughout, and in which:

Figure l is a side elevational view.

Figure 2 is a vertical sectional view showing the plunger moved inwardly to ll the measuring chamber.

Figure 3 is a similar view showing the valves andi plunger in dispensing position.

Figure 4 is a transverse sectional view taken on aline 4-4 of Figure 3.

Figure 5 is a transverse sectional view taken on a line 5-5 of Figure 2.

Figure 6 is a top plan view.

Figure 7 is a perspective view of a modified Wall bracket.V

Figure 8 is an enlarged fragmentary perspective view showing the bayonet slot for attaching the combined cover, glass holder and tooth brush holder.

Figure 9 is an enlarged perspective view of the notched Washer at the lower end of the valve stem.

Referring now to the drawings in detail where- 2. infor the purpose of illustration, I have disclosed a preierredembodiment of the invention, the numeral 5 designates a substantially hollow cylindrical` powder container having a sloping4 bottom 6 toward a central discharge opening 'l provided with a downwardly extending annular flange 8 to form a measuring chamber il at the bottom of the container.

\ The outer edge at the vbottom of the container is formed with anA annular rib I which is. seated in a groove Il of a supporting walll 'bracket I2', the bracket having a. verticalopening i3 in the upper end of which the, flange 8f projects. The bracket i2 includes a plate I4 formed on itsrear tace with a lug I5 having upper andy lower tapering horizontal grooves I6 and I1 therein.

The lugl I5 is received in an` opening I8 in the outer. surface of a box-like attaching plate L9 secured to a wall or other suitable supporting structure 2. The sides of the plate I9 are formed with vertical slots 2|v in which. the ends of a transverse pin 22 are slidably positioned to enter the upper groove I6 of the lugY while the lower groove I'Iy receives the loweredge of the opening I8 to thus lock. the plate I lvoi the bracket I2 to the attachingv plate I9.

A. hollow Valve stem 23 is'v slidablyv mounted in upper and, lower guides 24 and 25; extending` transversely of the container 5, the endsy of the lower guide 25 being secured in position. by vertical bolts 2-6. which have theirY lower ends an,- chored in the bracket I2'` and extend upwardly through the bottom 6 of the container.

A washer 2l isA held against a shoulder 2-8ad jacent the upper enel.r of; thev valve stein 2:3- by a coil spring 29 placed'` under compression between the washer and the upper guide 2li` to normally urge the valve stem. downwardly.

A lower conical valve 301 is held on the, lower end of valve stem 23 with its tapered-end positioned; upwardly by a notched disk 3l: suitably carried by the vaive stem. below the valve-1301;` the tapered end of the valve terminatinginani-ip.- wardly extending sleeve 32 which holds anupper downwardlyv tapering valve 33I on the valvestem against a shoulder 34. The lowerportonlot the valve 33 surrounds ther upper portion ofvsleeve 32 in spaced relation therefrom andthe valve stem 231 and sleeve4 32 areformed. with aligned openings 35v to vent the, measuring chamber 9.

The valves 30 and 33 are spacedverticallyone above the other and the valve 3Ilseats againstthe lower edge of the flange 8 at the bottom of the measuring chamber it while.Y the valve. 33 seats 56 against. the opening Vl. in the-bottom. 6 of; the

3 tainer to close the top of the measuring chamber 9. The valve is actuated by means of a plunger 36 slidably carried in the opening I3, the plunger having a vertical passage 31 therein which is flared at the upper end of the plunger as shown at 38, the lower end of the passage forming a discharge opening. The lower end of the valve stem 23 is positioned in the flared portion 38 of the plunger" whereby an upward movement of the plunger will engage the lower end of the valve stem to raise the valve 30 to close the lower end of the measuring chamber 9 and to raise the upper valve 33 to open the upper end of the chamber whereby to admit powder from the container 5 into the measuring chamber. A plurality of pins 39 project downwardly from the lower end of plunger 36 for engagementby the hand 40 of a person for raising the plunger, the pins preventing moisture from the hand contacting the plunger which might clog the discharge passage 31. When the pins 39 are released by the hand, the-spring 29 lowers the valve stem 23 to open the lower valve and close the upper valve 33 whereby the contents contained in measuring chamber 9 is discharged through the discharge opening 31 of the plunger into the hand of the person.

The hollow valve stem 23 vents the container to prevent creation of vacuum therein and the vent openings exhaust air from the measuring chamber 9 when the lower valve 30 is moved upwardly into its closed position.

The top of the container 5 is closed by a cap 4| provided with inwardly projecting locking pins 42 engaging bayonet slots 43 in the upper outer walls of the container to lock the cap in position thereon.

The top of the cap is recessed as shown at 44 to provide a holder for a glass 45 and the opposite sides of the cap are formed with outwardly projecting shoulders 46 having openings 41 therein for receiving toothbrushes 48 to support the brushes therein.

'In the operation of the device, the plunger 36 normally gravitates downwardly in the bracket I2 as shown in Figures 3 of the drawings free of the lower end of the Valve stem and the valve is held downwardly by the spring 29 to maintain the lower valve 30 open and to close the upper valve 33. An upward movement of the plunger 35 by the hand 40 of a person will simultaneously close valve 30 and open valve 33 whereby powder placed in the container will enter the measuring chamber 9. Y

' Upon releasing the plunger 36, the valve 33 will be closed and the valve 30 simultaneously opened and the powder contained in the measuring chamber 9 will be discharged into the plunger 36 and out through the discharge opening 31 into the hand of a person held beneath the container.

Figure 7 illustrates a modified construction of the attaching plate and comprises a block 49 of suitable material and adhesively or otherwise suitably attached to a wall. Vertical slots 50 are formed in the sides of the block for receiving the locking pin 5|"held in the slots by a face plate 52 suitably secured to the block. Registering openings 53 and 54 are formed in the block and face plate respectively for receiving the lug l5 of bracket I2. A lug 55 is formed on the block 49 for engaging a notch 56 in the face plate to center the plate thereon.

1 In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention what is claimed as new is:

1. A dispenser of the class described comprising a powder container having a discharge opening in its bottom, an annular flange extending downwardly from the opening to form a measuring chamber, a valve stem slidably mounted in the opening and extending downwardly through the chamber, an attaching bracket supporting the container and having a vertical opening into which the lower end of the valve stem projects upper and lower valves carried by the stem closing respectively the top and bottom of the chamber to trap powder therein, said valves being arranged for opposite opening and closing movement, and means for vertically actuating the valve stem, said means comprising a funnelshaped plunger slidably mounted in the opening of the bracket and positioned beneath the chamber and engaging the lower end of the valve stem to open the upper valve and close the lower valve -upon an upward movement of the plunger, spring means lowering the valve stem, and manually engageable actuating pins projecting from the lower end of the plunger to protect the plunger from contact with the hand of a person actuating the plunger.

2.
